METHOD FOR AUTOMATICALLY CALCULATING INSULATION THICKNESS OF BOILER USING CALCULATION FORMULA

摘要

PURPOSE: A method for automatically calculating an insulation thickness of a boiler using a calculation formula is provided to save manpower needed for calculating the insulation thickness by easily calculating the optimal insulation thickness of the boiler and minimize a calculation error by systematically arranging considerable factors for each item. CONSTITUTION: A quality and the thickness of the insulation/refractory, emissivity of a coated material for the insulation/refractory, a convection coefficient of each application part are inputted, and at least one from an outer diameter, an inner temperature, and an outer temperature is inputted in case of a pipe(S10). Estimated surface/boundary layer temperatures are fixed(S12). Heat transfer is calculated. The surface temperature and the boundary layer temperature are calculated/verified(S16). In the case that the calculated temperature is identical with the verified temperature, the thickness of the corresponding insulation is fixed(S20).
